Signal Demodulation Methods for Electrical Tomography: A Review

IEEE Sensors Journal, 2019
The amplitude and phase of each sinusoidal frequency component in a signal can be obtained by phase-sensitive demodulation, which is commonly used in electrical tomography (ET) and greatly influences the performance of the ET system. In the past decades,

A Digital Demodulator for PSK Signals

IEEE Transactions on Communications, 1973
This paper describes a digital demodulator for phase-shift-keyed (PSK) signals in which the phase difference between the received signal and a carrier reference is found by measuring digitally the time interval between the zero crossings of the signal and the reference.

An adaptive demodulation for OFDM signal

2016 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2016
This paper presents a novel method for OFDM demodulation based on LMS adaptive filter. In this proposed method, data symbol is reconstructed from amplitude of reference signal without using fast Fourier transform and thus this method can be applied for real time system.

Demodulation of cochannel QAM signals

International Conference on Acoustics, Speech, and Signal Processing, 2003
The authors describe a technique for demodulating a quadrature amplitude modulated (QAM) signal in the presence of a second cochannel QAM interferer and intersymbol interference. The method consists of a two-step procedure whereby tentative estimates of both the desired and interfering signals are made and then converted into final estimates by ...

Parallel demodulation of multidimensional signals

IEEE Transactions on Communications, 1992
The design of constellations that allow a high degree of parallelism in the staged decoder structure and in addition allow soft decoding of the component algebraic codes based on a systolic algorithm amenable to VLSI implementation is considered. Combination of these multidimensional constellations with trellis-coded modulation (TCM) is also considered.

Demodulation of suppressed signals

Proceedings of the IEEE, 1977
A demodulator is proposed that exploits the by-produced image of a weak signal, which is suppressed by a strong interfering one in a bandpass limiter, to recover 3-dB from the well-known 6-dB weak-by-strong-signal suppression effect.

Signal Demodulation: Problems

2013
Modulated waveform must be received and the message recovered. The message recovery in AM communication systems requires a circuit that is capable to extract the carrier envelope. A diode–capacitor based circuit known as envelope detector (or, peak detector) is essential part of both AM and FM receivers, as well as many other analog signal processing ...
